Procedure For Overspeed Verification
Start the engine and run the engine at rated speed. Enter service mode. Enter the password. "OP 1" is showing on lower display. Refer to Systems Operation, "Service Mode" for more information. Refer to Systems Operation, "Password Entry OP3" for more information.
Press "SCROLL UP" key eight times. "OP 9" is showing on the lower display.
Press "SELECT" key. The value of overspeed setpoint P10 is showing on the upper display. "SC1" is showing on the lower display. "SC1" is followed by the present engine speed value.
Press "SELECT" key. The setpoint value is flashing on the upper display.
Decrease the value of the setpoint by pressing the "SCROLL DOWN" key. The value is flashing on the upper display. The default setting from the factory is 2120. The setpoint value decreases by 10 rpm with each press of the scroll down key. Continue pressing the key until the value of the setpoint is lower than the current engine speed. The current engine speed value is shown on the lower display. When the setpoint value is less than the current engine speed, the engine shuts down. The indicator for engine overspeed will be flashing. The GSC is not in service mode.Procedure For Low Oil Pressure Verification
Note: Service mode cannot be entered when the ECS is in the AUTO position.
Start the engine and run the engine at rated speed. Enter service mode and enter the password. "OP 1" is showing on lower display. Refer to Systems Operation, "Service Mode" for more information. Refer to Systems Operation, "Password Entry OP3" for more information.
Press "SCROLL UP" key eight times. "OP 9" is showing on the lower display.
Press "SELECT" key. The value of overspeed setpoint P10 is showing on the upper display. The default setting from the factory is 2120. "SC1" is showing on the lower display. SC1 is followed with the current engine speed.
Press the "SCROLL UP" key once. The value of the P13 setpoint for low oil pressure shutdown at rated speed is showing on the upper display. The default setting from the factory is 205 kPa (30 psi). "SC2" is showing on the lower display. SC2 is followed by the present oil pressure value.
Press "SELECT" key. The setpoint value is flashing on the upper display. The default setting from the factory is 205 kPa (30 psi).
Press the "SCROLL UP" key in order to increase the value of the setpoint. The setpoint value is flashing on the upper display. The setpoint value increases by five with each press of the "SCROLL UP" key. Continue pressing the key until the setpoint value increases past the present oil pressure. The present oil pressure value is showing on the lower display. When the setpoint value is greater than the present oil pressure value, the engine shuts down. The indicator for low oil pressure will be flashing. The GSC is no longer in service mode.Procedure For High Water Temperature Verification
Note: Service mode cannot be entered when the ECS is in the AUTO position.
Start the engine and run the engine at rated speed. Enter service mode and enter the password. "OP 1" is showing on lower display. Refer to Systems Operation, "Service Mode" for more information. Refer to Service Manual, "Password Entry OP3" for more information.
Press "SCROLL UP" key eight times. "OP 9" is showing on the lower display.
Press "SELECT" key. The value of overspeed setpoint P10 is showing on the upper display. The default setting from the factory is 2120. "SC1" is showing on the lower display. "SC1" is followed by the current engine speed.
Press "SCROLL UP" key two times. The value of the P15 setpoint for high water temperature shutdown is showing on the upper display. The default setting from the factory is 107°C (225°F). SC3 is showing on the lower display. SC3 is followed by the present coolant temperature value.
Press "SELECT" key. The setpoint value is flashing on the upper display. The default setting from the factory is 107°C (225°F).
Decrease the setpoint by pressing the "SCROLL DOWN" key. The value is flashing on the upper display. The setpoint value decreases by five degrees with each press of the "SCROLL DOWN" key. Continue pressing the key until the setpoint value decreases past the present coolant temperature value. The present coolant temperature value is showing on the lower display. When the setpoint value is less than the present coolant temperature value, the engine shuts down. The indicator for high water temperature will be flashing. The GSC is no longer in service mode.
